Phase 1: Excavation

What Happens First?

When we pull into your driveway we hope to see your kids waiting with their bathing suits on because that’s when we know it’s going to be a fun job! 

Our team will be driving two vehicles: a work truck towing a skid steer(or bobcat), and a large dump truck towing our excavator.  We use the excavator to dig the hole and lift and set the pool.  The skid steer is used to move dirt and gravel. 

The first thing the crew will do is paint the pool on the ground and use a laser level to establish how high to set the pool in the yard.  This will tell us how deep to dig the hole. We’ll then position the dump truck close to the hole (if needed) and begin excavation. 

While one crew member digs the hole the others begin to work on setting the pump and filter system. Excavation of the hole usually takes between three hours and one and a half days, depending on the size of the hole and how long it takes to dispose of the dirt. 

Phase 2: Placing the Gravel Foundation

After the excavation is complete, we will place a 2″ thick layer of gravel in the hole which the pool will rest on. This gravel base determines the height of the pool so we use a laser level to set the gravel at precisely the right elevation.  We are usually at this point at the end of day one or the beginning of day two of construction.  

It’s important to note that we use gravel instead of sand for the installations.

Phase 3: Plumbing the Pool and Filter System

What is the filter system?

The filter system is composed of two major components: the pool pump and the filter.  The pump circulates the water and the filter removes debris and small particles from the water.  At the filter system you also typically find other elements such as valves that control the flow of water, salt water chlorinators if you have one, a switch for the pool light, and a heater if desired.

Where is the Filter System Typically Located?

Usually within thirty to sixty feet from the pool, but it can be much further away if the site dictates.  If possible, it’s best to locate the pool equipment (i.e. filter system) at the house, preferably somewhere inconspicuous.  It’s also not uncommon to locate it in the yard, somewhere out of plain view. 


Phase 4: Backfilling the Pool Shell

Once the plumbing is complete and the pool is set in the hole and leveled it’s time to start filing the pool with water and backfilling around the outside with gravel. 

It’s important that the gravel on the outside and the water on the inside are brought up together to equalize the pressure.  It’s also important to install what’s known as a drain pipe during this phase of construction.  The drain pipe is an 8″ PVC pipe that extends from the top of the patio to the bottom of the excavation.  There is no permanent pumping system installed, this pipe simply allows us to access any ground water around the pool in the event the pool requires draining in the future. 

Usually by the time we begin backfilling the pool the electrician will have begun wiring the pool equipment.  Ideally, the pump and filter system will be wired so we can start circulating the water as soon as the pool is full, although sometimes there are circumstances that prevent this.

What type of gravel do you use to backfill the pools?

The type of gravel used for backfiling around a fiberglass pool is critical.  We use clean crushed blue stone roughly 3/4″ – 1″ in size.  Clean in this regard, means that the gravel is free of fines, also known as stone dust.  Gravel with stone dust would not compact when we dump it in the hole and therefore would require manual compaction….which is exactly what we’re trying to avoid with sand.  

Clean crushed stone compacts when placed, it drains very well, and the point on point friction between the pieces of stone lock together allowing it to hold well on the side walls of the pool.  This is why we prefer crushed stone over pea gravel which is round and acts like little ball bearings on the outside of the pool and can more easily slide down the pool wall if and when the pool is drained.  

Usually by the end of day two or three our team has the pool shell installed and full of water with all of the plumbing completed, and this completes initial installation phase of construction.  Before beginning the coping and patio work we will need an inspection.  This is also the point at which we would install waterline tile on the pool if specified. 

Depending on weather and our schedule, it’s not unusual to have a delay of one to two weeks between the completion of this initial phase and the beginning of the next major phase of construction, the coping and patio. 

Phase 5: Coping and Decking

With the pool completely backfilled and inspections approved our team is ready to install the coping around the top of the pool shell and the pool patio.  There can be a delay of a few days to two weeks before the patio crew arrives depending on weather and inspection schedules.  The patio can take anywhere from two to five days to install depending on the size of the patio and material used.  

One of the most important roles of the patio is locking the pool shell into place. 

Phase 6: The Pool Fence

With the pool installed and the patio complete, we’re on the home stretch.  The typical project at this point has been in process for anywhere from two to five weeks depending on the weather.  All we need now to wrap everything up is an approved pool fence. 

Installation Summary

  1. The total process usually takes anywhere from three to six weeks for a typical project. 
  2. The type of material used under and around the outside of the pool is critical.  Based on our experience we feel gravel is the way to go.
  3. Setting and leveling the pool correctly is imperative if you want your pool to look great and last a long time.
  4. How the pool and patio tie together is extremely important.  Our methodology, Rhino-Loc Construction, utilizes composite Rhino rods to fuse the pool and patio together.
  5. And finally, we want to see your kids in bathing suits when we arrive.
